WINCH.

1,150,351. Specification of Letters Patent.

Patented Aug. 17, 1915. Application filed January 25, 1915. Serial No. 4,276.

To all whom it may concern Be it known that I, THOMAS L. ELMonE, a citizen of the United States, residing at Baker, in the. county of Santa Rosa and State of Florida, have invented certain new and useful Improvements in Winches, of which the following isa specification, reference being had to the accompanying drawesr' o; This -invention relates to certain improvements in winches; and an object of the in- ,vention is to provide a novel and improved device of .this character of a portable-type and wherein a maximum of pull may be created with. a minimum-of parts. Furthermore, it is an object of the invention to provide a device of this character having novel and improved means whereby the same may be power driven, operated or manually operated, in accordance with the necessities of practice.

It is also an object of the invention to provide a device of this character having noveifand improved means whereby the opings, l-l denote skids dis osed in parallelism and in predetermined spaced relation and tied or connected at adjacent extremities by the cross tie or beam 2, said tie or beam projecting, as indicated at 3, beyond one of the skids and adapted to have mounted on such projected portion 3 a suitable motor at preferably of an internal combustion type.

Intermediate their lengths, the skids 1 are further tied or connected by the lower member 5 of the frame F, adjacent ends of the members 5 and 6 of the frame converging as'indicated at 7 and having interposed between'their outer extremities the block 8 with which an anchoring member 9 is adapted to coact, as is believed to be clearly shown in the accompanying drawings. The upper member 6 of the frame is reinforced by the brace members 10 while interposed between such members 5 and 6 adjacent their inclined extremities are the sleeves 11 surrounding the vertical bars 12 members 5 and 6 are further.

maintained in their separated relation.

35, erati'ng means for the winding drum may be Rotatably supported between the memadjusted into or outof engagementwith the bers 5 ad 6 and positioned therebeneath is drum with convenience and facility.

The invention consists in the details of construction and in the combination and soarrangement of the several parts of my improved winch whereby certain important advantages'are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more'fully set 'forth.

The novel features of the invention will carefully defined in the appended claim. In'order that my invention may be the feo better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure'l is a top plan View of a winch const'ructed'in accordance with an embodiment of my invention; Fig. 2 is an elevational view oftlie'dvice' as disclosed in Fig. '1, with additional operating means shown applied theretofFigB is-an enlarged fragmentary viewfpartly in section and partly eo jn plan, illustrating'in detail the means for operatively engaging .the,drum with the rotating mechanism"th'ere for; and Fig. 4 is an enlarged 'fra'gmentary view, 'partly in I, section an d fpartly inelevation, of the strucfie ture disclosed-particularly in Fig. 3.

As disclosed "inthe accompanying drawthe flanged drum 14, the periphery of the lower flange being toothed, as at 15, and adapted to be operatively engaged by the pinion 16 carried by the shaft 17 rotatably supported by the members 5 and 6 and projecting a predetermined distance above the upper member 6. The lower extremity of the shaft 17 is received within the elongated longitudinally disposed bearing slot 18 produced in the lower member 7 whereby it will be perceived that the gear or pinion 16 may be adjusted into or out of mesh with the drum 14. This adjustment is especially desirable in order to permit free retrograde movement of the drum when it is desired to unwind the pulling member 19, herein disclosed as a flexible member, having one extremity suitably secured to the drum. In order that the shaft 17 may be suitably adjusted so as to create the desired mesh between the gear or pinion 16 and the drum 14, or more particularly the teeth 15 thereof, I provide the lower member 5 with the transversely disposed recess 20 intersecting the slot 18 and in which is slidably mounted the cam or wedge member 21 which serves, upon inward movement, to impart the requisite transverse movement to the shaft 17. In order that the cam or wedge member 21 may be conveniently adjusted, I have one whereby said extremity thereof pivotally engaged, as at 22, with the upstanding lever 23 having its lower end portion pivotally engaged, as at 21, with one of the skids 1.

Projecting upwardly from the upper member 6 and positioned above the sleeves 12 and maintained in operative position by the bars 14 is the bearing 25 in which is rotatably supported the horizontally disposed shaft 26 also operatively engaged Within the I The shaft 26 between the bearings 25 and 28 has fixed thereto a sprocket wheel 31and a drum 32 whereby said shaft may be operatively engaged with the motor I either by a belt ora sprocket chain, of-practice may require, I also find it of advantage to have the outer extremity of the shaft26 angular in cross section so that a crank 33 may be conveniently applied there- -to whereby said shaft may be manually rotated under such conditions when the motor 4 cannot be used. I also find it of advantage to have the upper extremity of the shaft 17 squared to. permit a conventional sweep 35 to be operatively engaged therewith whereby, when required, draft animals may be employed for operating my improved winch and, in which event, the shaft 26 with the worm 29 is removed or the worm 29 otherwise disengaged fr om the gear 30.

VVhile'I have herein described and illustrated in the accompanying. drawings. the shaft 26 provided with a worm 29 coacting witha face gear 30, I wish it to be understood that other forms of gearing may be employed with equal facility by resorting to such changes which clearly fall within the scope of my present invention and without creating an inventive act.

as the requirements In actual practice, a winch constructed in accordance with my invention is meeting with great success, especially in extracting stumps, log skidding and pulling boats out on dry docks, and in view of the different usages to which it may be put, I do not desire to be understood as limiting my invention, as herein disclosed, to any particular usage.

. From the foregoing description, it is thought to be obvious that a winch constructed in accordance with my invention is of an extremely simple, and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

A device of the character described comprising a supporting member, a frame carried thereby and including vertically spaced members, adjacent extremities of the members converglng, a bearing carried by the upper member, a bearing operatively supported by the converging extremities of the members, a horizontally disposed shaft rotatably supported by the bearings, a drum rotatably supported by and between the members of the frame, a vertically disposed shaft carried by said members and adapted for operative engagement with the drum, and means for operatively connecting the horizontally disposed shaft and the vertically disposed shaft, said horizontally disposed shaft being provided with operating means.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. THOMAS L. ELMORE.
